Hi there. Electrical issues like you are describing are typically caused by a constant parasitic drain. In most cases, this is due to an accessory relay that is faulty, allowing the component to constantly draw power from the battery. It could be other electrical problems causing this issue, so before you attempt any more repairs, it’s probably better money spent to have one of our mobile mechanics come to your location to complete a battery won’t hold a charge inspection. This will allow them to isolate the source of the drain and recommend the right repairs.

If your Dodge Grand Caravan battery warning light comes on while driving, be sure to turn off your accessories, so the battery doesn`t deposit further. The warning light usually means that the alternator isn`t working accurately meaning you are operating solely on battery power.
If the battery is in a good state, the multimeter should show a reading between 12 and 13 volts. Measure the starting voltage of your Grand Caravan: With the tips of the multimeter in the same position, and without breaking contact, we must turn the engine on and check how much the voltage drops when the engine starts.
If your Dodge Grand Caravan battery warning light comes on while driving, be hopeful to turn off your accessories, so the battery doesn`t discharge further. The warning light consistently means that the alternator isn`t working appropriately meaning you are operating absolutely on battery power.
An illuminated battery indicator can be caused by a number of issues, including: A loose or corroded battery cable. A problem with the alternator or voltage regulator. Damaged cells or plates inside the battery.
There are many reasons why your battery light could turn on. It could indicate a bad battery or dead battery, a charging problem, a faulty alternator, a wiring issue, and so on. And while driving with the vehicle`s battery light on is possible, it`s not recommended.
If the measured reading is less than 12.2 volts, the battery`s resting voltage is weak, which means it most likely needs to be charged or replaced.
What Voltage Should My 12v Battery Show? A fully charged 12 volt battery should read at 12.6 volts on the multimeter. If the reading is lower than this, you`ll want to charge your battery with either a battery charger or by taking your car for a drive.
Can I Keep Driving My Car if the Battery Light Is On? Yes, you can, for a short time. The light indicates that the alternator isn`t charging the battery, which means your car`s electrical system isn`t getting the needed power.
A dashboard battery light basically means there`s a battery charging problem. Your car isn`t getting enough voltage from the car battery to operate properly.
You will need a leisure battery in order for most of the 12V appliances in your caravan or motorhome to function but, even if it wasn`t essential, there is a very good reason for choosing to use a leisure battery rather than powering the devices directly from a mains charger or similar.
Depending on your type of battery, you can achieve 20 to 300 cycles (Flooder or Cheap), 400 to 500 cycles (gel) or 600 to 800 cycles ( AGM), while batteries with 5-year-guarantee give 1,000 cycles. Whenever your battery charge falls below 75% re-charge it; never let it level fall below 50%.
A leisure battery will be essential to power the appliances and equipment in your caravan or motorhome, providing a power source for the 12V appliances. It will be required to provide a steady level of power over a prolonged period of time, to power the likes of: The lights.
It is possible that the problems that you have been experiencing with the bad alternators have damaged the battery causing it to be weak. This would make the Battery Light come on. It is also possible that there is a problem with the fusible link or the alternator fuse for the charging system.
I did a bit of research and found a battery reset is required to resolve the issue. The message can reset by itself, but the car needs to sit undisturbed for at least eight hours. Perhaps with your work/driving schedule the car doesn`t sit long enough.
The red battery light basically means that there is an issue with your alternator, your battery, or some other part of the charging system which could be as minor as cabling or as major as a computer malfunction.
Some cars will get up to five or six years out of their battery, while others will need a new one after only two years. In general, your car will usually need a new battery after three to four years. Replacing your car battery is another part of routine maintenance.
Load Testing
As long as battery voltage remains above 9.6 volts, the battery is considered “good.” But if it drops below 9.6 volts by the end of the test, the battery may be “bad,” or the battery may have to be recharged and retested if it was not fully charged prior to the test.
For a car with a 12V engine, the normal value before starting is between 11.9V and 12.8V, and it should not exceed 14.8V after starting.
It is unsafe to drive with your car battery light on. Issues that activate your car battery light, like a defective battery or faulty alternator, can cause your car to lose power. In these instances, your car won`t operate as it normally would.
If your alternator is failing, its voltage may drop below capacity, causing the battery warning light to appear on your dash. Similarly, the battery light will also appear if the alternator is exceeding its voltage limit, depending on how much stress it is under.
